A new index for quantifying the ornamentational complexity of animals with shells. [PDF]
Ecol Evol, 2022 We proposed an ornamentation index (OI) derived from 3D scanning technology and a virtual model for quantifying ornamentation complexity. This index is designed to measure the extent of folding associated with ornamentation, regardless of shape and size.

Can fractal dimensions objectivize gastropod shell morphometrics? A case study from Lake Lugu (SW China). [PDF]
Ecol Evol, 2022 In our study, we compare established morphological and morphometrical methods to the new approach of fractal geometry with respect to a group of freshwater gastropods from Lake Lugu (China) as a model group. Our results show that fractal geometry can help to overcome shortcomings of these established methods, since it might help to objectivize shell ...

Cortical complexity estimation using fractal dimension: A systematic review of the literature on clinical and nonclinical samples. [PDF]
Eur J Neurosci, 2022 Abstract Fractal geometry has recently been proposed as a useful tool for characterizing the complexity of the brain cortex, which is likely to derive from the recurrence of sulci–gyri convolution patterns. The index used to describe the cortical complexity is called fractal dimensional (FD) and was employed by different research exploring the ...

Understanding 3D structural complexity of individual Scots pine trees with different management history. [PDF]
Ecol Evol, 2021 Crown‐segmented point clouds of individual Scots pine trees (A bottom) and an example of classified point clouds representing a Scots pine tree (A top center) with the fitted 3D convex hull enveloping the crown points, viewed from the top (A top left) and side (A top right). The definition for the box dimension for the same Scots pine (B), the slope of

The Journal of Physiology, Volume 601, Issue 18, Page 4033-4052, 15 September 2023., 2023 Abstract Figure Legend Despite subtle sex differences in cardiomyocyte structure and calcium fluxes, the differences are balanced, leading to similar calcium transients in cardiomyocytes from male and female mice. Abstract Sex differences in cardiac physiology are receiving increased attention as it has become clear that men and women have different ...

Extended GOSIM: MPS‐Driven Simulation of 3D Geological Structure Using 2D Cross‐Sections
Earth and Space Science, Volume 9, Issue 6, June 2022., 2022 Abstract In the past two decades, algorithms for multiple‐point statistics (MPS) have been applied in many fields. However, 3D training datum or data (TD) is difficult to be obtained. Two‐dimensional geological cross‐sections from boreholes or geophysical data with high reliability are usually used to explain geological phenomena and are relatively ...

An Adaptable Random Forest Model for the Declustering of Earthquake Catalogs
Journal of Geophysical Research: Solid Earth, Volume 127, Issue 2, February 2022., 2022 Abstract Earthquake catalogs are essential to analyze the evolution of active fault systems. The background seismicity rate, or rate of earthquakes that are not directly triggered by other earthquakes, directly relates to the stressing rate, a crucial quantity for understanding the seismic hazards.

Reef‐building corals act as long‐term sink for microplastic
Global Change Biology, Volume 28, Issue 1, Page 33-45, January 2022., 2022 To investigate whether tropical shallow‐water reef‐building corals can act as long‐term sinks for microplastics, we exposed four common reef‐building coral species to polyethylene microplastics for 18 months in a microcosm experiment. We found that reef‐building corals permanently incorporate microplastics into their skeletons, acting as unique ...

Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022 This work is devoted to present a generalized complex discrete fractional Gaussian map. Analytical and numerical analyses of the proposed map are conducted. The dynamical behaviors and stability of fixed points of the map are explored. The existence of fractal Mandelbrot and Julia sets is examined along with the corresponding fractal characteristics ...

Cellular Oncology, 2006 The fractal nature of the DNA arrangement has been postulated to be a common feature of all cell nuclei. We investigated the prognostic importance of the fractal dimension (FD) of chromatin in blasts of patients with acute precursor B lymphoblastic ...
